Chapter 9 Major Positioning Control
Positioning data setting example
[When "2-axis circular interpolation control with sub point designation (INC circular
sub)" is set in positioning data No. 1 of axis 1]
• Reference axis............. Axis 1
• Interpolation axis.......... Axis 2 (The required values are also set in positioning
data No. 1 of axis 2.)

Set "Positioning complete" assuming the next
positioning data will not be executed.
Da.2

–
INC circular
sub
–
Set incremental system, 2-axis circular
interpolation control with sub point designation.
Da.3
Acceleration time No.
1 – 1 –
Designate the value set in "
Pr.25
Acceleration
time 1
" as the acceleration time at start.
Da.4
Deceleration time No.
0 – 0 –
Designate the value set in "
Pr.10
Deceleration
time 0
" as the deceleration time at deceleration.
Da.5
Axis to be interpolated
QD77MS2 QD77MS4
Axis 2 –
Set the axis to be interpolated (partner axis).
If the self-axis is set, an error will occur.

–
Set the speed during movement. (Designate
the composite speed in "
Pr.20
Interpolation
speed designation method
".)
Da.9
Dwell
time 500ms – 500ms –
Set the time the machine dwells after the
positioning stop (command stop) to the output
of the positioning complete signal.
Da.10
M code 10 – 10 –
Set this when other sub operation commands
are issued in combination with the No. 1
positioning data.
Da.20

Setting not required (setting value is ignored).
(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
POINT
Set a value in " Da.8 Command speed" so that the speed of each axis does not
exceed the " Pr.8 Speed limit value". (The speed limit does not function for the
speed calculated by the QD77MS during interpolation control.)
